We're not sure we've seen cleaner Boss pedals here in the shop than this Boss NS-2 Noise Suppressor (along with some other Boss pedals from the same collection). 

The classic noise gate effect is perfect for taming unwanted hum from high gain effects or amplifiers. Simple controls and parameters make dialing in the suppression/gate quite easy as well.

It's hard to call this one used when you consider its condition! This is a totally mint example complete with the original box!
